Is it OK to put regular gas in a premium car?
It's a different story for a car whose engine requires premium fuel. The car will run on regular fuel in a pinch, but you shouldn't make a habit of it. The fuel's lower octane can result in elevated exhaust-gas temperatures and possible knocking, both of which can adversely affect the engine's health in the long run.

Does premium gas last longer than regular gas?
Sadly, there's nothing in premium gasoline that would make it last longer than other fuels from the pump. Since the distinguishing feature is the higher-octane levels, the only real benefit you gain is lowering the chance of engine knocking, which isn't much of a threat on most modern fuel systems.
Does premium gas burn faster?
Engine Suitability: Regular unleaded gas burns faster than premium gas, which is why it works better with engines that have low compression ratios. If your vehicle's engine has a high compression ratio, it is best to use premium gasoline.
Why do cars need premium gas?
So if premium gas is better at resisting self-ignition, who needs it? Most cars just don't have the high performance requirements (meaning a high compression engine) that will cause knocking in a modern engine - and preventing that knocking is why you need the high octane gas. Only a small number of vehicles really need it, and these are mostly sports cars.
What is the octane rating of gas?
The octane rating of gas is a measure of how good it is at resisting that self ignition. The lower the rating, the more likely it is to self ignite.
What Are the Different Grades of Gas?
Every time you drive past a gas station, or stop to fill your car or truck, you'll see three (and sometimes even four) different grades available. These are two obvious differences between the grades:
What Happens if Gas Self Ignites?
A potent fuel is exploding (in a very small way!) in a semi-uncontrolled fashion. As with any explosion, it causes vibration and shock waves, which can ripple throughout the car engine. You'll notice this as a knocking or a pinging sound. Imagine repeatedly hitting your car's engine with a small hammer - it'd have a similar effect. If a lot of knocking occurs, it could potentially damage the engine.
Where Does The Octane at the Pump Come In?
Modern technology has made huge changes in how car engines perform, and they are much more capable of self correcting for minor problems today. That also means they don't have to have a very high compression ratio, unless you have a car which is designed to be very high performing - in other words, a sports car.
How does a car engine work?
A traditional car uses an internal combustion engine, and it works like this. A mixture of gas and air is compressed by the motion of a piston inside a cylinder. When it's compressed to a certain point, a spark sets it on fire and the tiny explosion sends the piston back up the cylinder. There are several cylinders, each with a piston, and every one is pumping up and down to keep producing power for the car.
What does "self ignite" mean in a car?
In a modern car engine this is very precisely timed, but there's still sometimes some fuel that, because of the high heat produced by this action, might detonate ("self ignite" or "pre-ignite") before the spark sets it off at the exact right time.
What is the difference between premium and regular gas?
The main difference with premium is its octane rating — 91 or higher compared with 87 for regular octane. The higher octane gives premium gas greater resistance to early fuel ignition, which can result in potential damage, sometimes accompanied by audible engine knocking or pinging. Higher octane allows engines to have higher compression ratios (for a more energetic explosion), more advanced ignition timing or forced-air induction like turbochargers or superchargers. They perform best when fed premium fuel.
Why do I burn premium?
If you burn premium because you think it makes the engine peppier, that is probably psychological: “I’m paying more for gasoline, so I must be getting more.” Some motorists claim they get better fuel economy with premium, but some of that could be due to favorable weather conditions (such as warm weather instead of cold) or other factors.
Does premium gas boost acceleration?
If your engine runs fine on regular, filling it with premium is unlikely to boost acceleration or fuel economy by more than insignificant amounts.

Does 87 octane make a car faster?
But if the vehicle manufacturer says your engine needs only 87-octane regular, that is what you should use. The higher octane of premium gas won’t make your car faster; in fact, the opposite is possible because higher-octane fuel technically has less energy than lower-octane fuel. It’s the fuel’s ability to be compressed more without pre-igniting ...
What is premium gas?
What Premium Gas Does. Premium gas, which usually has an octane level of 92 or 93 ( compared with regular's octane level of 87), is designed to prevent knock on cars with high compression ratios. The compression ratio is the total volume inside the cylinder that is displaced when the piston moves. If you use low-octane gas on a car ...
What happens if you don't use premium gas?
In fact, if your car doesn't say anything about premium gas usage, all you'll be doing is dumping more money into your car. Premium gas will do nothing to increase the performance of a car that wasn't designed for it, so don't waste your money.
How to find out what your car requires?
The best way to find out what your car requires is to—surprise—look in the owner's manual ! If your car requires premium gas: Then you need premium gas. Your car has a high compression ratio and, moving to a lower grade will likely cause knocking, which you really don't want. Advertisement.
Can you use premium gas in a car?
If your car recommends premium gas: This is trickier. Years ago, says Edmunds.com, it more of an all-or-nothing deal, but many cars today have internal knock sensors that change the game. Now, many cars can adjust the engine's timing to prevent knock, thus allowing you to use lower octane gasoline if you so choose. If your car merely recommends premium gas, you can safely switch to a lower octane without risking engine damage. You will notice a small drop in performance—as in, it'll take you a half a second longer to accelerate from 0 to 60—but since I'm not trying out for Fast and the Furious XCVIII, I've never bothered. Some argue that this level of precision could make it easier to merge on the freeway or avoid an accident, though, so it's up to you to decide whether the extra money is worth the extra half second. Some say it can also improve your mileage, but again: you'll have to measure your mileage before and after against the increased cost to see if it makes a cost effective difference. Our brother site Jalopnik makes a good point, though— in a lot of places, premium gas is still pretty affordable when compared to the low-octane alternative.
Can low octane gas cause a rattle?
If you use low-octane gas on a car with a high compression ratio, it's more likely that the gas will ignite prematurely, causing your engine to knock and rattle (if you want a more in-depth view of how a car engine works, check out HowStuffWorks' article on the subject ). A mild knocking isn't necessarily harmful to your car, ...

What is a mistimed explosion?
A mistimed explosion, also said as “pre-ignition” or engine knock is known by these names because it simply sounds like knock or ping. A high gasoline resists the engine knock. When mistimed combustion takes place, the vehicle emits lower-level pings. An occasional ping most likely will not harm your vehicle, but repetitive knocking demise the car’s engine. Perhaps because of this condition, earlier people put premium gas in a regular gas car.
What does octane mean in gasoline?

Why do cars change timing?
Modern cars are often able to change the engine timing to allow them to use lower octane gas. That means it can operate smoothly on the lower octane fuel without engine knock problems. Therefore, you will not be risking engine damage. On the other hand, using the lower octane and changing the timing likely means a minor drop in performance. You might see less responsive acceleration or possibly even a slight decrease in fuel economy.
What is the difference between premium gas and regular gas?
Regular gas is rated at 87 octane in most states, while premium gas is often rated higher at 91 or 93. Fuel with a higher octane rating can stand up to higher compression before it detonates. Essentially, the higher the octane rating, the lower the likelihood that detonation happens at the wrong time. On occasion, this occurrence will likely not harm your vehicle. However, if it happens frequently it may quicken the decline of your engine's performance.
What happens when you use a lower grade of fuel?
